==Data Types==The following data types are used for specifying the storage layout:
==infThe following tables present the layout of BaseX database files. All files are suffixed with <code>.basex==</code>.
'''Contents==Meta Data, Name/Path/Doc Indexes:''' Meta information on a database and main memory indexes.<code>inf</code>==
'''Contents* <code>tbl</code>:''' Main database table and , stored in blocks.* <code>tbli</code>: Database directory, organizing the database blocks.
'''Contents* <code>txt</code>:''' Heap file with text values (document names, string values of texts, comments and processing instructions)* <code>atv</code>: attribute values.
'''Contents* <code>txtl</code>: Text index:''' Heap file with attribute valuesID lists.* <code>txtr</code>: Text index: Index file with references to ID lists.* <code>atvl</code>/<code>atvr</code>: Attribute value index, using same logic.
'''Contents:''' Value index for texts...will soon be reimplemented.
'''Contents:''' Value index for attributes. ==(ftxa|ftxb|ftxc).basex== '''Contents:''' Trie full-text index. ==(ftxx|ftxy|ftxz).basex== '''Contents:''' Fuzzy full-text indexwill soon be dismissed.
